Question

I need a regular expression to extract from two types of URIs

http://example.com/path/to/page/?filter
http://example.com/path/to/?filter

Basically, in both cases I need to somehow isolate and return

/path/to

and

?filter

That is, both /path/to and filter is arbitrary. So I suppose I need 2 regular expressions for this? I am doing this in PHP but if someone could help me out with the regular expressions I can figure out the rest. Thanks for your time 🙂

EDIT: So just want to clearify, if for example

http://example.com/help/faq/?sort=latest

I want to get /help/faq and ?sort=latest

Another example

http://example.com/site/users/all/page/?filter=none&status=2

I want to get /site/users/all and ?filter=none&status=2. Note that I do not want to get the page!

Using parse_url might be easier and have fewer side-effects then regex:

$querystring = parse_url($url, PHP_URL_QUERY); 
$path = parse_url($var, PHP_URL_PATH);

You could then use explode on the path to get the first two segments:

$segments = explode("/", $path);
